Water Pressure Tank Air Valve

The air will trigger the piston inside the gauge and measure the air pressure within the tank.

Water pressure tank air valve.

Unscrew the cap covering the valve and press the tire gauge down on the valve. When water pulses at the spigot it usually means you have a waterlogged tank. Pressure relief valves for water these valves are commonly used with pumps in low pressure water systems. Water tank pressure measured at the air gauge or schrader valve on the tank top will creep up to above normal levels.

Use a small screwdriver to depress the air valve to see if water comes out. Design a valve specifically for your process media and set pressure. Choose from a valve for air inert gas water hydraulic oil fuel oil gasoline or diesel fuel and a set pressure from 150 to 3 300 psi. Bleeding air out from the tank top will prove a short remedy and pressure will creep up again.

A new tank costs about 200 and up. A common cause is a failed check valve. The air inlet valve on a bladderless water pressure tank may be at any of several locations. At left is an air inlet valve located on the tank tee near the bottom of what was a bladderless water pressure tank.

If the valve fails water streams back down the well and the pressure switch turns the pump on again. The internal water tank air valve stem part valve stem core that is replaced can be purchased with different spring strengths for different pressure ranges but in fact given that the pressure range of a typical water tank is 20 70 psi like a car tire almost any common tire valve stem core would work fine as a replacement if your valve stem won t stop leaking. The check valve or foot valve prevents the well pressure tank from sending water back down into the well after it has built up with water pressure. Replacement is your only option.

Water tank air inlet valve schrader valves. The tank pressure should be within 10 of the original factory water tank pressure setting. Unscrew the plastic cover from the air valve on the top of the tank. Near the tank top on the tank side on a tee at the bottom of the water tank or on well piping nearby.

Check the pressure tank s air valve. On composite tanks the valve can be found toward the base of the tank.
